Yes, I was watching them; alas they could not prevail and are now dust with their neighbours who incidentally activated them. I use developer mode to cut down on the Invader/Precursor/Star Swarm conflicts, (sometimes all three in the same system).

Don't forget the hoop snakes. They ate all the Drop Bears in Melbourne !

Australia is now but a memory, I managed Sydney, Blue Mountains, Brisbane, Perth and the entire West coast to Darwin, then Kakadu and Arnhem land. Trip of a lifetime, but still lots more I would like to visit.
